How to Use Claude AI: A Complete Beginner's Guide (2026)

TL;DR :

Claude AI is far more than a chatbot. This guide shows how to use Claude AI across Chat, Cowork, and Code modes, plus Projects, Skills, and Office plugins. Whether you want to automate tasks, write code, or organize files, Claude handles it all.

Introduction

Most people who try Claude AI for the first time do not know what to do with it. They type a question, get an answer, and then close the tab thinking it is just another chatbot. That is the wrong first impression, and this guide is here to fix it.

If you have ever wondered how to use Claude AI for real daily work — not just chatting — you are in the right place. By the end of this article, you will understand what Claude can actually do, which features are worth your time, and how to get started without any technical background.

Here is what this guide covers:

• The three main modes in Claude: Chat, Cowork, and Code

• Four built-in features that separate Claude from other AI tools

• How to use Claude inside Excel and PowerPoint

• A practical alternative for developers who need flexible API access

• Answers to the most common questions people ask about Claude

What Claude AI Can Actually Do for You

Most people think Claude is a tool for programmers. That is only half true. Yes, Claude Code is one of the strongest AI coding tools available right now. But the rest of Claude — meaning Chat and Cowork — is built for people who have never written a single line of code.

Here are a few things Claude can do that go beyond simple conversation:

• Send a task from your phone and have it completed on your home computer before you arrive at the office

• Live inside your Excel spreadsheet as a sidebar and analyze data without you switching apps

• Learn your weekly report format once and reproduce it automatically every week after that

• Write, debug, and refactor an entire codebase using plain English commands in your terminal

• Organize your Downloads folder by file type without you lifting a finger

These are not hypothetical examples. They are built-in features you can use today.

How to Use Claude: The Three Main Modes

Claude runs on web, mobile, and desktop. For everyday users, the desktop app offers the most complete experience. Download it at https://claude.com/download — it is free to start.

Once you open the desktop app, you will see three tabs at the top: Chat, Cowork, and Code. All three serve a different kind of need, and understanding the difference is the fastest way to get real value from Claude.

Chat Mode: More Than Question and Answer

Chat is the default interface. It looks familiar if you have used any AI assistant before. But Claude's Chat does a few things others do not.

When you ask for a comparison table, Claude does not give you a wall of text. It generates an interactive visual chart directly in the conversation panel. Ask it to build a simple tool like a Pomodoro timer, and it creates a working, clickable widget right there alongside your chat. Claude calls these outputs Artifacts, and it was the first major AI tool to introduce them. You can download or share them immediately.

Claude also lets you switch between three models depending on what you need:

• Haiku is the fastest option, good for simple questions

• Sonnet balances speed and quality, and is the best choice for daily use

• Opus is the most capable model, suited for complex or demanding tasks

Most users will be well served by Sonnet. Upgrade to Opus only when the task genuinely requires deeper reasoning.

Cowork Mode: How to Use Claude AI as a Task Executor

Cowork is where Claude stops being a conversation partner and starts being a worker. The difference matters.

In Chat, you ask Claude something and it tells you what to do. In Cowork, you give Claude a task and it does it for you — on your actual computer, with your actual files.

Here is a real example. Instead of manually reading through a folder of event documents to write a sponsorship proposal, you point Cowork at the folder and say "write a sponsorship proposal using these materials." Claude scans the files, asks a few clarifying questions, breaks the task into steps, and then generates a finished presentation file directly on your hard drive. You can watch it work in real time on the right side of the screen.

Cowork also supports scheduled tasks. You can set it to summarize your emails every morning or compile weekly data every Friday. You set it once, and it runs automatically.

One additional feature worth knowing is Dispatch. This lets you send instructions from your phone while Claude executes them on your desktop at home. It is still in early preview and works best for simpler tasks, but the basic workflow is reliable: scan a QR code once, and your phone becomes a remote control for your computer.

Code Mode: How to Use Claude AI for Development Work

Code is Claude's third mode, and it is aimed squarely at developers. If you do not write code for a living, you can skip this section — though it is worth at least knowing it exists, because it explains why so many software teams are switching to Claude as their primary AI tool.

Claude Code runs in your terminal as a command-line tool. Once installed, you navigate to any project folder, type claude, and start giving it instructions in plain English. It reads your existing codebase, understands the structure, and then acts on it directly.

Some things you can ask Claude Code to do:

• Refactor a specific module to follow a different pattern

• Find and fix a bug in your payment processing logic

• Write unit tests for a service you just built

• Explain how a complex part of the codebase works

What makes this different from pasting code into a chat window is that Claude Code works with your full project context. It does not just answer questions. It makes changes, runs commands, and iterates based on your feedback — all from the terminal, without you switching between tools.

Claude Code also supports Computer Use on macOS, which means it can interact with applications on screen when terminal access alone is not enough. Before it takes any significant action, it asks for your approval.

One thing that makes Claude Code particularly flexible for teams is that it does not require you to use Anthropic's models exclusively. Through GPT Proto's Claude Code integration, you can point Claude Code at the GPT Proto API and run a different model behind the interface — including GLM-5, Kimi K2.5, DeepSeek, MiniMax, and over 160 others. The Claude Code interface stays exactly the same, but the model powering it changes. This is useful when you want to cut API costs, test different models on the same codebase, or avoid rate limits from a single provider.

The setup takes just a few minutes. You install Claude Code via npm, then point it to the GPT Proto endpoint using two environment variables. After that, you can assign different models to different task tiers — for example, using a powerful model for complex architecture decisions and a faster, lighter model for quick completions. You can see all available models for Claude Code on GPT Proto here.

Code mode is available on the desktop app and in the terminal. It is not available on mobile or through the web interface.

The Four Features That Make Claude AI Stand Out

These four features work across Chat, Cowork, and in some cases Code as well. Together, they turn Claude from a one-time tool into a long-term work partner.

Projects give Claude a dedicated workspace for each area of your work. Instead of explaining your context at the start of every conversation, you build a project once — upload your reference files, write your custom instructions, set your rules — and Claude remembers everything from that point on. ChatGPT has a Projects feature too, but it does not support the same level of custom instructions or file depth.

Skills are reusable instruction sets. If you create a weekly report using a specific format and structure, you can package that process as a Skill. The next time you need the report, one sentence is enough. Skills work across different projects, which makes them far more flexible than anything in ChatGPT's GPTs or Google's Gems. Claude also has a Skills marketplace where you can install ones other users have already built.

Memory lets Claude learn your preferences over time. As you chat, it picks up on how you like things worded, what formats you prefer, and what your usual requests look like. Claude manages memory by project, so preferences in one workspace do not bleed into another. You can view, edit, or delete any memory entry at any time.

Connectors link Claude to your existing tools. It currently supports over one hundred services including Google Workspace, Notion, Slack, and Canva. What makes Claude's connectors different is that they work in Cowork and in the Office plugins, not just in Chat.

How to Use Claude AI Inside Excel and PowerPoint

Claude has dedicated plugins for Microsoft Excel and PowerPoint, available through the Microsoft App Store. Once installed, a Claude sidebar appears directly inside these applications. You do not need to leave the document to get help.

Inside Excel, Claude can analyze data across multiple sheets, explain formulas, and maintain relationships between cells when you change values. Inside PowerPoint, it can reformat a text-heavy slide into a clean visual layout that matches your existing color scheme and branding — automatically.

The most powerful combination is using both together. You can tell Claude to pull a specific data range from your Excel file and insert it as a chart into your PowerPoint presentation. That entire process takes one instruction.

A practical two-step workflow that many users find effective:

1. Use Cowork to do research, sort materials, and produce a first draft presentation

2. Open that file in PowerPoint with the Claude plugin and refine it against your company template

This takes you from raw materials to a polished, on-brand document without manual formatting work at any stage.

Why Some Users Are Looking for a Claude AI Alternative

Claude is a strong, well-rounded tool. But it is a subscription product with a monthly fee, and its Cowork features require the desktop app to be open and running. For developers or teams that need more flexibility — including the ability to connect different AI models, control costs, or integrate Claude Code with alternative backends — a platform like GPT Proto is worth considering.

GPT Proto is a unified AI API platform that gives developers and businesses access to over 200 models through a single interface, including Claude Sonnet and Claude Opus. Rather than managing separate API keys and accounts for each provider, you connect once and route requests wherever they are needed. This is especially useful when you want to compare models, maintain uptime through automatic failover, or build workflows that combine Claude with other tools.

You can browse available models including Claude on GPT Proto directly. The platform uses a pay-as-you-go structure rather than monthly subscriptions, which can be significantly more cost-effective for teams with variable usage. Pricing for Claude models through GPT Proto runs at roughly 50 to 80 percent below direct provider rates.

For teams already using Claude Code in their development environment, GPT Proto's Claude Code integration guide walks through exactly how to connect the two. The platform also supports Grace, a desktop automation agent built on top of the GPT Proto API, which covers similar ground to Claude's Cowork for users who want more control over their setup.

Here is a quick comparison to help you decide which path fits your needs:

If you are a solo user who wants something that works out of the box, Claude's paid plans make sense. If you are building something or managing AI access across a team, GPT Proto's model library gives you more room to work.

FAQs About How to Use Claude AI

Is Claude AI free to use?

Yes. Claude has a free tier that includes Chat, Projects, Memory, Skills, Connectors, and web search. The free version has usage limits and does not include the Opus model or Cowork. The Pro plan at $20 per month adds Cowork, Dispatch, the Excel plugin, and Computer Use. The Max plan at $100 per month adds the PowerPoint plugin and the Opus model. Claude Code is available as a separate tool and can be used independently of the subscription tiers.

How do I use Claude AI on my phone?

Claude has a mobile app for iOS and Android. The mobile app supports Chat and gives you access to Projects, Memory, and Connectors. Cowork and Code mode are only available on the desktop app. If you have set up Dispatch on your desktop, you can send Cowork instructions from your phone and they will run on your computer remotely.

How is Claude different from ChatGPT?

Both tools handle general conversation, writing, research, and coding tasks at a high level. Claude's main advantages for everyday users are Cowork (which executes tasks directly on your computer), deeper Projects with custom instructions, cross-project Skills, and Claude Code for terminal-based development. ChatGPT has a larger plugin ecosystem and is more widely integrated into third-party tools. Neither is objectively better — it depends on how you plan to use it.

Can I use Claude Code with models other than Claude?

Yes. Through GPT Proto's Claude Code integration, you can run Claude Code while powering it with a different model from the GPT Proto network — including DeepSeek, Kimi, GLM, MiniMax, and many others. The Claude Code interface stays the same, but you control which model handles the actual requests. This gives development teams more flexibility over cost and model selection without changing their workflow.

Conclusion

Knowing how to use Claude AI well means understanding that it is not just a chatbot. It is a three-mode system — Chat for thinking and creating, Cowork for executing tasks on your computer, and Code for building and maintaining software from the terminal. Underneath all three modes, Projects, Skills, Memory, and Connectors make the whole thing more useful the longer you use it.

For most people who want an AI assistant that actually does work rather than just talks about it, Claude is one of the best options available in 2026. Start with the free plan, get familiar with Projects and Skills, and upgrade only when you hit the usage limits.

If you are a developer or you need to run Claude at scale across a team, the direct subscription may not be the most efficient path. GPT Proto gives you Claude AI API access to Claude and over 200 other models in one place, with transparent per-use pricing and no monthly lock-in. You can explore Claude models on GPT Proto here and see current pricing against market rates. For Claude Code users specifically, the GPT Proto integration makes it easy to swap in alternative models without changing a single line of your development workflow.

The AI landscape in 2026 is less about which model is the smartest and more about which tools actually help you get things done. Claude, used properly across all three of its modes, is one of the tools that earns its place in your workflow.
